If your date is a badboy like Kellan Lutz, he’s going to want to break the rules. Just make sure he does so tastefully. Exhibit A: Calvin Klein shiny dinner jacket with black matte dress pants and a long navy-blue tie. Add some hardware with the belt, and he’s cool, not crass.

We would like to give a round of applause to Joe Jonas for most daring Red Carpet look. At the premiere, Jonas stepped out in a Simon Spurr glen plaid suit. Notice that he pairs his statement-making print with a clean white shirt, and nothing else. If ties are mandatory, go with a solid.

Usher’s Emporio Armani three-piece suit is a total hit! The R&B star looks absolutely dapper with the contrast piping and dark buttons. Usher manages to pull off mid patterns with a checked shirt and tie but if you want to play it safe, tell your date to go with just one pattern in the ensemble!
